To all whom it may concern:

Be it known that we PETER J. CHRISTMAN, J r., and JAMES DELoYE, both citizens of the United States, and residents of Green Bay, in the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Sheet-Folding Machines; and we do hereby declare that the followin is a full, clear, andexact description thereo The invention relates to devices for cutting and folding paper. It comprises parent rolls for receiving webs of paper, V-plates for making a fold in each of the webs, pull rolls for feeding the web to a cut-01f roll, a tucker, rolls for receiving the paper after the tucking operation, a fence which directs the folded sheets to an oscillatory packer, and a receiving magazine on either side of the packer.

The primary object of the invention is the procuring of an especially rapid cutting and folding action without creating danger of multilating the paper or otherwise impairing the operativeness or general utility of the mechanism. With this in view, the machine is constructed, firstly, to act on two webs of paper simultaneously. Secondly, the cutting action is expedited by the provision of two blades on a rotary carrier,

which obviously operate to perform the cutting action more quickly than one blade alone. Thirdly, the folding operation is made especially rapid, two tuckers being provided on the rotary carrier. These tuckers are of simple character and the single stationary cam is adapted to actuate both of them, giving them a quick slap. A spring returns the tuckers to inactive position.

An object of the invention is an advantageous arrangement of parts of which there is a minimum number. The transmission of power is positive, a minimum of friction occurring.

Additional ob ects are the-nlcety of adjustment of parts and the provision of a construction durable and not apt to get out of order readily.

With the above and other objects in view, which will appear as the description proceeds, our invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, we have illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode we have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a side elevation of the machine.

Figure 2 is a side elevation at right angles to Flgure 1.

Figure 3 is a cross section on the line 3--3 of Figure 4, and

Figure 4 is a cross section on the line 4-4 of Figure 1. r

The frame comprises vertical supports 10, four in number, transverse members 11, 12, and 13, and elongated spacers 14 beneath which lugs 15 extend. Top member 16 is bolted to supports 10, as are, also, adjusters 17, which are provided with slots 18 for the lateral adjustment of rods 19, 19', 20, and

20', which support V-plates 21 and 21.

The V-plates receive the webs of paper drawn over parent rolls 22 and 22 mounted suitably to rotate on top member 16 and operate to produce a fold thereln, the paper then being compressed by pull rolls 23, the ends of which are journalled in blocks 24 adjustable by threaded rods 25 and nuts 26 in guide 27, these parts bemg mounted on transverse members 12 and 13. From the terminal projections 46 are mounted. Pin-' ions 37 mounted to rotate with said terminals 46 mesh with segmental gears 38 pivoted at 39 and provided with rollers 40 adapted to contact with cam 41, which en- 3 velopes shaft 42 with which carrier 30 is -rigid, earns 41 being secured to transverse member 12 by lug 43. Shaft 42 is free to rotate in cam 41. Springs 44 act on segmental gears 38 and tend to withdraw tuckers 45 to the position shown at the up er part of Figure 3.

n the rotation of carrier 30 on shaft 42, segmental gears 38 are moved by reason of the contact of rollers 40 with cam 41. In the position shown in Figure 3, blade 33 is cutting the web of paper extending between carrier 30 and cutting roll 28 and needle 34 is engaging the end of the web above the plates where the cutting action occurs. The lowerroller 40 has just been actuated by the projection 46 of cam 41 and caused tucker 45 to descend in a very rapid manner, slapping the paper between receiving rolls 47, thus producing a fold in the sheet. Simultaneously with this action the paper is detached from needle 34.

As there are two blades and two tuckers, two severing actions occur on each rotation of carrier 30 as do also two folding operations. Immediately below receiving rolls 37 1s a fence comprising a plurality of rows of guides 48 and 49 spaced apart slightly and secured by lugs 50 and 51 to rods 51 and 52 secured to supports 53. The paper is directed through the fence from receiving rolls 47 and contacts with bands 54, the ends of which rest on floor 55 of magazines, the sides 56 of which are provided with flanges 57 adapted to prevent the withdrawal of the folded sheets of paper after they have been moved into the malgazines by oscillatory packers 58 movin through the fence and between flanges 5 an extreme limit of movement thereof being shown in Figure 1.

Packers 58 are secured to bar 59 by arms 60 directed therethrough and threaded to receive nuts 61 on their ends. Bars 59 are secured to a air of oscillatory members 62 and 63 keyed to shaft 64. The ends of pull rolls 23, cutting roll 28, shaft 42, receiving rolls 47, and shaft 64 are journalled in the sides of the frame.

Power is received on'pulley 65 rigid with shaft 42 and rotates gear 66, also rigid therewith, which meshes with gear 67, rigid with the end of cutting roll 28, so that carrier 30 and cutting roll 28 operate in unison. The other end of cutting roll 28 is provided with a sprocket 68 enveloped by chain 69 extendinig over sprocket 70 rigid with the end of receiving roll 47, the other end of which carries a gear 71 operating to rotate the other receiving roll 47.

On the left hand end of shaft 42, as viewed in Figure 2 plate 72 is secured thereto to which a similar plate 73 is adjustably secured, plate 73 being provided with slots 74 and plate 72 having posts 75 thereon, receiving nuts 76 adapted to contact with plate 73. Rod 77 is rotatable on pivot 78 on plate 73 and its other end receives pivot 79 in block 80, which is movable on threaded rods 81' rigid with member 63, nuts 82 serving to ad ust block 81 so that the leverage of rod 77 may be altered and the limit of oscillation of packers 58 varied as desired.

Upon rotation of the pulley 65, which is fixed to the shaft 42, movement is transmitted to the carrier 30, and by means of the gears 66 and 67 rotation is imparted to the roll 28, which in turn, through the chain connection 69, imparts movement to the receiving rolls. The rod 77 eccentrically connected to the plate 73, which is carried on the shaft 42, serves to oscillate the packers 58 and alternately store the folded stock into opposite compartments.

We claim 1. A carrier having cutting blades secured thereto, a plurality of tuckers semi-rotatable on said carrier, said carrier being cut away to receive said tuckers, a plurality of segmental gears iyoted to said carrier, a roller on the end 0 each of said segmental gears, a stationary cam cooperating with said rollers to move segmental gears, and means cooperating with said segmental gears for moving said tuckers into tucking position.

2. In a paper folding machine, the combination of a rotating carrier, a pair of receiving rolls adjacent said carrier, an oscillating tucker carried by said carrier, means for actuatin'g said tucker to cooperate with said receiving rolls and fold the stock into the bite of said rOllS, a pair of stationary, spaced, vertical ides positioned beneath said receiving rol l s for the reception of the folded stock, a pair of magazines positioned on opposite sides of said guides, a support beneath said guides for the reception of the folded stock, said support connecting the magazines, and an oscillating packer for removing the foldedstook from the guides and alternately feeding it to opposite magazines.

3. In a paper folding machine, the combination of a rotating carrier, a pair of. receiving rolls adjacent said carrier, tucking means carried by said carrier and cooperating with said reeeiving rolls to fold the stock, vertical guides positioned beneath said bination of a pairaf stationary V-shaped folding plates set oppositely and at aminclination, a si e pair of pull rolls spaced l beneath said fiiIding platefs, a rotating car-- rier, tucking means extending longitudinally throughout the carrier, a pair 0 receiving.
